Tried to swap the air bleeder valves back to the OEM screws but the M8 insert that threads into the fork cap will not separate from the M4 bleeder. The insert is soft and will damage with too much holding pressure so I would prefer to replace it but can't find the part. The Marzzochi PDF doesn't show the insert, it looks like the M4 bleed screw threads into the fork cap. A search on the forum and Google didn't show anything so I'm hoping someone might have come across this before me?
I'm fairly sure they're the same as KTM WP 48600058 for the screw 48600009 o-ring. Here's one out of my 2005 Shivers.
Sounds like you’re on the right track. That insert sticking out of the top of your fork needs to come out. The bleeder screw will thread into the fork cap. Should be able to find the screw at most hardware stores. Mine also have an O ring around the screw. Good luck with getting the insert out, hopefully it’s not stuck in there.
Thanks for the part numbers Snafu, I have 4860s on my old airhead GS, I checked them and the light bulb came on, it was a classic case of over thinking on my part. Because the speed bleeder separates in the centre I was looking at it wrongly. Screws are back in place. Thanks for helping switch the light on!
